A day in the life of an Ethiopian woman who scrapes hides the old-fashioned way.

On the edge of the western escarpment of the Ethiopian Rift Valley, we sit in awe, not of the surrounding environment--some of the world's most spectacular scenery--but of an elderly woman deftly manufacturing stone scrapers as she prepares food, answers an inquisitive child, and chats with a neighbor. She smiles at us, amused and honored by our barrage of questions and our filming of her activities.

In our world of electronic and digital gadgetry, it is surprising to meet someone who uses stone tools in their everyday life. Yet, over the past three decades, researchers have identified a handful of ethnic groups in Ethiopia's southern highlands whose artisans live by making stone scrapers and processing animal hides.

In 1995, with colleagues from Ethiopia's Authority for Research and Conservation of Cultural Heritage and the University of Florida, we surveyed the highlands and, much to our surprise, identified hundreds of stone tool makers in ten different ethnic groups.

The Konso, one group we surveyed, grow millet and other crops on terraces and raise livestock that provide the skins for the hide workers. While hide working in virtually all of the other groups is conducted by men who learn from their fathers, among the Konso the hide workers are women, taught by their mothers or other female relatives.

Clearly, the Konso hide workers are a rich source of information from which we can address a range of questions: Can excavations of abandoned hide worker compounds provide insights into the identification of social inequality and ranking? How and in what social contexts is stone toolmaking learned? Can we differentiate women's activities from men's on the basis of stone tools?

There is a sense of urgency in our work. Many of the hide workers are elderly and have not taught their children their craft; the influx of plastic bags and Western furnishings have greatly reduced demand for their products. We want to complete our study of the Konso hide workers as soon as possible and begin studying other groups in southern Ethiopia whose hide workers are still using flaked stone, for after 2.5 million years of stone tool use and probably more than 100,000 years of scraping hides with stone, humanity's first and longest-lasting cultural tradition is rapidly being lost.
